Typhoon squadrons at a Scottish base will log an extra 300 flying hours each following the Ministry of Defence's bases reshuffle.
And £3.4 million per squadron will be spent to keep Typhoon jets at RAF Lossiemouth, Moray, as opposed to RAF Leuchars, Fife.
Former defence secretary Liam Fox announced the changes to the bases in July as part of a wide-ranging defence review.
The extra hours and costs reflect the greater distances and travel times to ranges and training areas from RAF Lossiemouth. Lossiemouth will become Scotland's only RAF base when the changes come into effect.
But in a written answer to former Liberal Democrat leader Sir Menzies Campbell, Defence Minister Peter Luff said the move had been made for sound reasons.
He said: "Flying time between bases and range or training hours can vary according to the training activities pursued in transit.
"It was judged these and other costs associated with relocating the Leuchars Typhoon at RAF Lossiemouth were outweighed by wider savings and other benefits to defence."
